IP WatchDog Lite monitors two independent channels (each channel controls one of the two relays) where it detects responses from remote device to ICMP command - PING. In case of remote device drop-out, the IPWatchDog activates the relay. This way you can restart device, shut it down for a specified time or start for example a back-up circuit.
Detection of remote device's function:
- Monitored device receives a PING that is sent periodically from IP Watchdog.
- Monitored device sends PING periodically to IP Watchdog's IP address.
